The SPEAKER (14:54): I just want to make a statement to the House before the Deputy Prime Minister resumes his answer. There's been a number of occasions now where the Manager of Opposition Business has moved that the Deputy Prime Minister be no further heard and he has done that under standing order 80. As members will know, I'm required to put that motion immediately without debate, which we've done on each occasion. I have also made clear, I think, on the first occasion when there was a dispute about the clock, which I think we have got past, that— Government members interjecting— The SPEAKER: No, members on my right, if this continued, potentially the Leader of the House could move every time the Leader of the Opposition asked a question that he be no further heard. Question time is designed for openness and accountability. It's a central feature of the day, where ministers are questioned. I'm now going to refer members to standing order 78, which does say: Should any of these questions be negatived— which they have today— no similar proposal shall be received if the Speaker is of the opinion that it is an abuse of the orders or forms of the House, or is moved for the purpose of obstructing business. So I am ruling now that I will not be accepting any further motions this week. The Deputy Prime Minister can resume his answer. Mr JOYCE: I thank the honourable member for his question— The SPEAKER: The Deputy Prime Minister will resume his seat. The Manager of Opposition Business.
